(AP) Federal scientists forecast that Oklahoma will continue to have the nation's biggest man-made earthquake problem in 2017 but it probably won't be as shaky as recent years. In its annual national earthquake outlook, the U.S. Geological Survey reported Wednesday that a large portion of Oklahoma and parts of central California have the highest risk for a damaging quake this year: between 5 and 12 percent.

USGS seismic hazard chief Mark Petersen says Oklahoma's recent regulation of wastewater injection is starting to work, so scientists slightly reduced Oklahoma's risk this year.
